The fixing base includes a base plate and a placement platform fixedly installed on the four sides of the base plate. The base plate has holes and slots, and a plurality of parallel elastic fixing components are provided on one of the placement platforms.

[0006] The adjustment assembly is fixedly installed on the fixed base, and the adjustment assembly includes a movable adjustment plate, which controls the size of the clamp.

[0007] The ejection assembly is located below the fixed base, and the ejection assembly includes a liftable ejection plate, which is used to eject the circuit board.

[0014] Compared with related technologies, the flexible circuit board assembly fixture of this utility model, through innovative modular design, comprehensively realizes three core functions: flexible clamping, adaptive size adjustment, and non-destructive ejection. While improving assembly efficiency, it effectively ensures the processing quality of precision electronic components. Its beneficial effects are specifically reflected in the following aspects:

[0015] This invention provides a clamp for assembling flexible circuit boards. Through an elastic fixing assembly consisting of sliding pillars, spring groups, and rubber pads, combined with a sliding grip control mechanism, multi-point flexible clamping is achieved. The compression plate automatically compensates for circuit board thickness tolerances under spring action, and the rubber pad contact surface effectively disperses clamping stress, significantly reducing the risk of damage such as micro-cracks and deformation. The distributed clamping structure formed by multiple independently operating elastic components can adapt to the contour features of irregularly shaped circuit boards.

[0016] This invention provides a fixture for assembling flexible circuit boards. Based on the principle of threaded transmission, the adjustment component allows for precise control of the clamping width via a knob. A sliding pair guide structure between the adjustment plate and the base ensures smooth and offset-free adjustment. Combined with the auxiliary limiting function of the telescopic column, it significantly improves adjustment accuracy and repeatability. This design allows the fixture to adapt to flexible circuit boards of different sizes and specifications, shortening changeover and debugging time and meeting the needs of multi-variety, small-batch production.

[0017] This invention provides a fixture for assembling flexible circuit boards. The ejection assembly employs a motor-driven linear lifting mechanism, achieving precise control of the ejection height through threaded transmission. The optimized ventilated structure on the ejection plate surface effectively eliminates the vacuum adsorption effect, and combined with a reasonable lifting stroke setting, significantly reduces the peeling force. The combined motion design of the guide mechanism and telescopic column avoids lateral stress during ejection, ensuring the complete removal of the ultra-thin circuit board.

[0018] This invention provides a fixture for assembling flexible circuit boards. The layered layout design of the modules ensures that clamping, adjustment, and ejection operations do not interfere with each other. The finger groove design of the grip and the damping adjustment characteristics of the knob meet ergonomic requirements, simplifying the one-handed operation process. The timing linkage control between the ejection mechanism and the clamping system forms a coherent operating logic, significantly improving clamping efficiency. Attached Figure Description
